Parametric modeling and optimization of NACA63418 airfoil
In wind turbines,the aerodynamic efficiency of wind turbines is closely related to the aerodynamic performance of excellent airfoils.Taking the conventional airfoil of wind turbine as the research object,combined with airfoil parametric modeling and self-adaptive genetic algorithm,the high performance optimized airfoil is obtained.The fitting accuracy of the conventional NACA63418 airfoil is compared between the CST method and the improved Hicks-Henne type function method,and then the Hicks-Henne type function method is selected to model the NACA63418 airfoil.The automatic calculation of aerodynamic characteristics of airfoil is realized by the coupling of self-adaptive genetic algorithm and XFOIL software,and the design efficiency of airfoil is improved.It broadens the train of thought and improves the design efficiency for the theoretical design of airfoils.
